The battery is not working, or the device is off. The battery is not getting enough power or the wrong charging cable is connected. The battery has errors or is not connected properly. If no charging cable is connected, may indicate it needs to be charged. The device has problems with the battery, not enough voltage, or not getting a charge. There's no standard for indicating the status of a battery using LEDs, but many companies follow these de facto standards. If this doesn't help, there's a problem with the cable. If it's the correct charger cable, disconnect and reconnect both ends of the cable and connect the cable directly to the wall. In this situation, make sure you're using the correct charger cable. Some laptops (e.g., ASUS and Dell) may also have a white and amber blinking LED when the incorrect charger cable is connected, or it's not firmly connected and not supplying enough voltage. When this happens, there's usually a problem with the laptop motherboard (power interface board), cable, or battery. With laptop batteries (e.g., Dell and Lenovo), a blinking or flashing LED light that's green or orange indicates there's an issue related to the battery. As the card is used (e.g., browsing the Internet), data is sent to and from the network card, and the LED flashes to indicate communication.
However, when a cable is connected, the LED lights up as a solid green LED. For example, without a cable connected to a network card, it shows an orange LED or no LED. The LEDs on a network card, network switch, and network router indicate when a connection is made and when data is being transferred. Network card, Wi-Fi, switch, and router LED To find the meanings of these LED numbers and letters, reference your motherboard manufacturer manual. For example, a Q-Code of "5A" indicates an internal CPU error.
For example, ASUS motherboards have a Q-Code LED that displays a two-character hexadecimal code to indicate the motherboard's state. Some motherboards have an LED that creates a number to indicate a POST code or status code that indicates the state of the motherboard. When the power cable is disconnected from the computer, the LED light stays on for several seconds and then slowly fades off, which is normal.
